Welcome Guest to Charlie's FlyBox!
Bloom Caddis
step: 1
Pattern Description
This unconventional little parachute caddis pattern comes from the vise of Dave Bloom of Montana's Missouri River. Dave is a contract tyer for Idylwilde Flies and his patterns are in huge demand for the techy fish of the Big Mo. This is a cool pattern to tie and fish, its' hi viz para post making it easy to see and the unique golden pheasant rope body is a great match for many of our caddis species down Colorado way as well. Feel free to alter colors as needed to match up with your local bugs.
Materials Needed: All materials used here available for mail order. Please use the contact form for pricing and details.

Hook: TMC 921 is used on the original, but you have all come to know that I use the TMC 100SP-BL wherever I can, so that is what I have used here.>>>>> Thread: 8/0 UNI Camel>>>>> Body: Golden Pheasant Tail Fibers, twisted into a rope>>>>> Wing: Natural Yearling Elk Hair>>>>> Para Post: Cerise McFlylon>>>>> Hackle: Brown and Grizzly mixed, cree or grizzly dyed brown>>>> Thorax: Brown Superfine Dubbing or Natural Hare's Mask as used on the original
step: 2  
Start the thread at about the 75% point and wrap a thread base back to the bend. return the thread to the starting point.

step: 3  
Cut a healthy clump of golden pheasant tail fibers from the stem. Be sure to take these from more toward the center of the feather so the fibers have enough length to complete the body.

step: 4  
Clip the tip ends of the pheasant tail fibers square across their ends and tie them in at the seventy five percent point with a couple of firm wraps. Pull the tips down flush with the thread wraps.

step: 5  
Hold the pheasant tail fibers slightly toward you as you wrap back over them to the bend of the hook. Allow the thread torque to pull the fibers to the top of the hook as you wrap over them.

step: 6  
Roll the pheasant tail fibers in your fingers to coil them into a cord. Don't twist them up so far that they start to double back on themselves, but make sure they form a nice, tight rope.

step: 7  
Begin wrapping the coiled fibers up the hook. You may need to re-twist the fibers occasionally as you move forward.

Wrap the coiled fibers up to the seventy five percent point, tie them off with a couple tight wraps of thread and clip the excess.

step: 9  
Make a thread base from the front of the body up to the hook eye and back again to the front edge of the body in preparation for the hair wing. Cut, clean and stack a small clump of yearling elk hair, measure it against the hook so it reaches just past the hook bend.

step: 10  
Transfer the measured wing to your material hand while holding it tight against the top of the hook shank. Make two loose turns of thread over the hair right at the front edge of the body. These wraps should close down around the hair but not be so tight as to flare the hair yet. Keep the tips of the hair firmly in the fingertips of your material hand while making these wraps. Do not release the hair!

step: 11  
While still holding onto the wing tips, tighten the thread wraps by drawing the bobbin directly toward your chest. This will tighten the thread and flare the wing butts. Continue wrapping toward the hook eye with firm wraps through the wing butts.

step: 12  
Come in with the tips of your scissors and trim the wing butts as close to the hook shank as you can. Wrap a smooth thread base over the stubs to smooth the thorax area a bit.

step: 13  
Take a short piece of copper wire and wrap it around the shank, gently binding the hair wing down against the body of the fly. This will hold the hair out of the way while we post the parachute wing and wrap the hackle later.

step: 14  
Move the thread to the midpoint of the thorax section and tie in about a half strand of McFlylon with two diagonal turns of thread.

step: 15  
Turn the McFlylon so it is perpendicular to the shank and make two more diagonal wrap across its' center. You are tying the McFlylon in like spinner wings, with a set of X-wraps. Make sure the wraps are stacked on top of one another and present a clean cross in the middle of the wing.

step: 16  
Pull both halves of the McFlylon up above the hook and make two post wraps around the base, grouping the wings into one piece.

step: 17  
Select, size and prep a hackle feather and tie it in to the shank at the front of the wing base. There should be enough bare stem to wrap over it to the top of the thread base at the bottom of the wing post.

step: 18  
Wrap around the wing post and the hackle stem to the top of the post. There should still be about a half turn of bare stem left when you reach the top of the post. Wrap the thread back down to the base of the wing.

step: 19  
Dub a thin strand of dubbing onto the thread and begin wrapping it just behind the index point. we are going to dub from the front of the hook to the base of the hair wing.

step: 20  
Form the thorax with the dubbing, covering all the thread work in front of the hair wing and ending with the thread wrapped around the base of the parachute post. if you tie right handed this wrap around the wing post should be counter clockwise and left hanging on the far side of the hook.

Wrap the hackle feather from the top of the post to the bottom, packing several turns of hackle in tightly.

step: 22  
Pull the hackle feather down on the near side of the hook. Pick up the bobbin on the far side and make two turns of thread around the base of the parachute post, under the wrapped hackle. Take the thread and make a turn around the hook shank right behind the hook eye.

Clip the leftover hackle tip as closely as you can. Whip fiish the thread just behind the eye and clip it as well.

Clip the parachute wing into a shortish stub. remove the wire holding the hair wing down and add a drop of cement to the base of the wing post. You're done.
